Eastgate systems used to make a "3x5 Card Briefcase" to capture short notes on the go which could later "be scanned or transcribed to Tinderbox."

Tinderbox was one of the first digital tools to be used in a way very similar to zettelkasten of old, particularly by academics, who are a large portion of their power user base.
